My dear Sir

Are you likely to have the 2^d section of your paper finished in time to be read in the present Session of the R.S., which ends in June? If you are, it might be worth while to delay the reading of the 1^st Section till both could be read together: otherwise I consider that the description of the apparatus you have devised, & the illustration of its use afforded by its application to the experiments on the conduction of heat form of themselves a quite sufficiently important paper – I am led to make the inquiry by a reperusal of your letter of Feb^y 29^th, in which you have left to me to decide whether the first section should be read by itself, or should be reserved for the addition of the 2^d section – I scarcely feel able to judge on such a point myself.²

Are you restricted in your experiments by their cost? or if you had a grant of £50 from the Gov^t Grant of this year would it enable you to have more complete apparatus for them? If you were to state a definite object in your researches, & ask for a grant to the amount above stated, I am sure that it would be very favourably rec^d and would be very likely to be allotted.³ M^r Thomson of Glasgow & M^r Joule are applicants for sums to that amount from the £1000 at the disposal of the R.S. this year, for experiments on very kindred points to yours.

Sincerely yours | Edward Sabine

D^r Tyndall.⁴
